Note that if the `-DBUILD_TESTING=OFF` flag is passed then Abseil tests will not be run. + +You will need to provide Abseil with a Googletest dependency. There are two +options for how to do this: + +* Use `-DABSL_USE_GOOGLETEST_HEAD`. This will automatically download the latest +Googletest source into the build directory at configure time. Googletest will +then be compiled directly alongside Abseil's tests. +* Manually integrate Googletest with your build. See +https://github.com/google/googletest/blob/master/googletest/README.md#using-cmake +for more information on using Googletest in a CMake project. + +For example, to run just the Abseil tests, you could use this script: + +``` +cd path/to/abseil-cpp +mkdir build +cd build +cmake -DABSL_USE_GOOGLETEST_HEAD=ON -DABSL_RUN_TESTS=ON .. +make -j +ctest +``` + +Currently, we only run our tests with CMake in a Linux environment, but we are +working on the rest of our supported platforms. See +https://github.com/abseil/abseil-cpp/projects/1 and +https://github.com/abseil/abseil-cpp/issues/109 for more information. + ### Available Abseil CMake Public Targets Here's a non-exhaustive list of Abseil CMake public targets: |
